Novak Djokovic set up a blockbuster Australian Open quarter-final against Carlos Alcaraz but refused to do a post-match interview because of a row with the host broadcaster.
Djokovic has been riled by some of the fan behaviour at Melbourne Park and he was booed after declining to answer questions from former champion Jim Courier on court in the customary manner following his 6-3 6-4 7-6 (4) win over Jiri Lehecka, instead briefly thanking supporters for coming.
